This month's Lone Delver is a rather simple, but highlights one of the primary dangers faced by the solo delver: you're alone. The illustration is by Liz Danforth and is from Ken St. Andre's classic solo, Deathtrap Equalizer (2nd edition). There is no slavering monster or fiendish dark magic depicted, only a delver stuck at the bottom of a pit. Despite the "commonness" of the situation it can be just as deadly as a charging balrog.
A major hazard of solo delving is that there is no one around to help when you get in a tight spot, like the bottom of a pit. If you're with a group, you can rely on your comrades to help pull you out (at least you hope so). But if you're alone you can shout for help all you want; if you're lucky no one will answer your cries, if you're unlucky something might and your probably would not like the result. So what's a solo delver to do? Equip yourself. Bring a rope and a grappling hook. Bring a hammer and some pitons. Be self reliant. Make sure that if you fall into a pit you have the means to get yourself out. The only thing that goblin that wanders by is going to do is laugh at you, and maybe throw some rocks for fun.
